Haha did you even stop for a second to question where those stats were coming from?
Scroll down to the bottom:

Browsers that count for less than 0.5% are not listed.

W3Schools is a website for people with an interest for web technologies. These people are more interested in using alternative browsers than the average user. The average user tends to the browser that comes preinstalled with their computer, and do not seek out other browser alternatives.

These facts indicate that the browser figures above are not 100% realistic. Other web sites have statistics showing that Internet Explorer is a more popular browser.

Anyway, our data, collected from W3Schools' log-files, over many years, clearly shows the long and medium-term trends.

You need to always be aware of where the data is coming from. In this case, it's solely from W3School log files, which is in no way representative of overall trends by users. So it shouldn't be a surprise to see the excellent representation of FF and Chrome.
